• Check the Fixture filters (see page 301).
• Is the DL.3 mounted less than 1.4 meters to an object? If so, move the DL.3
farther away to enable it to focus properly.
• Make sure the DL.3 is not operating near fog machines, hazers, or mineral
oil hazers (see See "Fog Machine Warning" on page 10.)
• Clean the front window (see Cleaning or Replacing the Front Window
on page 308).
• Check the lamp (see the projector manual shipped with the DL.3).
• If you're using the projector's on-screen programming system, you can
override zoom and focus using the menu system (see Projector Control
on page 243.)
• If the Blue LED is off, the Computer isn't receiving power. Press and hold
the Top and Bottom Tab select buttons to restart computer, (see Menu
Panel Components on page 23.)
• If the screen is not backlit, press the LCD power button, (see LCD Display
Adjustment Buttons on page 24.)
• Check the Video In Video Out adapter on the video card (middle plug)
connection.
• Check that the connectors for the composite video cable at the LCD Screen
and the Video card are seated securely.
• Verify that the last unit on the DMX link is properly terminated, (see Linking
DL.3 Fixtures on page 13.
• To control the DL.3 with DMX, you must first enable DMX through the menu
System (see DMX_Control Screen on page 30) or the CMA (see DL.3
and DL.2 Media Server Configuration Options on page 282).
• If you're using DMX to control the projector using its native menu system,
make sure you send a safe command after each button command;
otherwise, its analogous to pressing a button on the projector menu system
and not releasing it (see page Projector Control on page 243).
